Loading wxLua as library into standard lua interpreter
Summary
| wxLua can be loaded as package into a standard lua interpreter using “require”. |
This can be preferrable over using the interpreter that comes with wxLua, for example when an existing application is extended with GUI functionality.
The additional DLLs from the wxLua distribution are copied into the same folder as the lua binary.
The application needs to be modified a bit, as the example shows:
- wxLua needs to be loaded via require (first line)
- The wxLua main loop is entered using wx.wxGetApp():MainLoop() (last line)
Code
Download-- ******** Added: Load wxLua library *********
if not wx then require("wx") end
-- standard hello world application
local frame = wx.wxFrame(wx.NULL,
wx.wxID_ANY,
"wxLua used as library",
wx.wxDefaultPosition,
wx.wxSize(400, 200),
wx.wxDEFAULT_FRAME_STYLE
)
local panel = wx.wxPanel(frame, wx.wxID_ANY)
function OnPaint(event)
local dc = wx.wxPaintDC(panel)
dc:DrawText("Hello World", 100, 100);
dc:delete()
end
panel:Connect(wx.wxEVT_PAINT, OnPaint)
frame:Show(true)
-- ******** Added: Hand over control to wxLua *********
wx.wxGetApp():MainLoop()
